Improvement in spring bed-bottoms



UNITED STATES PATENT 'OEET L EDWIN S. FIELD, OF HARTFORD, CONNECTICUT.

IMPROVEMENT IN SPRING BED-BOTTOMS.

Specification forming part of Letters Patent No. 138,490, dated May 6, 1873; application filed. December 2, 1872.

GAsE A.

To all whom it may concern:

Be it known that I, EDWIN S. FIELD, of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Spring-Beds, of which the following is a specification, reference being had to the accompanying drawing.

I have for convenience sake divided the invention into two divisions, A and B, that part thereof described and claimed in this specification being included in division A.

In the drawing, Figure l is a top or plan view of part of the frame of a bed having one form or construction of my improved wire mattress attached thereto. Fig. 2 is a side view of such frame. Fig. 3 is a detachedenside rails c c, and have adjusting screws b 1),

whereby the tension of the mattress may be regulated. The other end piece rests in similar sockets attached to the other ends of the side rails. To the end pieces are attached spiral springs d, to the other ends of which is attached the wire-mattress or netting composed of V-shaped links 0 having hooked ends, each. of such hooks taking into the apex of the next succeeding link, forming as a whole a netting composed of continuous and connected diamond-shaped figures, which is very simple, strong, and efficient. T g

It will be observed that when downward pressure is applied to any particular link it draws not only in a direct line across the bed from head to foot, but sidewise in all directions, thus drawing more or less upon all of the spiral springs both at the head and the foot of the bed. 7

Instead of using these single V-shaped links a continuous wire, f, may be bent into a series of V-sha-pes, one series of the apexes being hooked, as shown in Fig. 4, such hooks taking into the plane apexes of the next wire similarly shaped, and so on. A peculiarshaped link g is used at the side of the netting so as to form a straight edge.

I claim as my invention 1. A wire netting composed of the V-shaped links hooked together, substantially as described, for the purpose set forth.

2. The peculiarly-shaped link 9 for forming the straight edges of the netting, having one long leg hooked so as to take into the angle of the next of these links, and one short leg running off obliquely, and hooked so as to take into the angle of one of theV-shaped links, substantially as and for the purpose set forth.
